Actions with Notes 1.8 will include option to flag with Today when you create a new Action

The next version of Actions with Notes will look like this when you compose a new Action:
The Today-button is only visible if you have configured the app to use the eProductivity template.
Clicking the Today button will let you toggle the Today flag on.

I would like to highlight the Talk to me button too. That's not a new button - it has been there since 0.1. It will display if you have the necessary bits installed for Voice-To-Text.
Clicking Talk to me will prompt you to speak, and then using Google cloud-based magic you will see what you just said in the Subject field. Mileage varies of course.
